Super Famicom (NTSC-J) and Super Nintendo (PAL) Barrel Size

Using the power of digital callipers and third party power supplies… too bad I didn’t have a first party power supply on hand. That’s probably why my inner barrel of the PAL unit was off by 0.1mm.

Super Nintendo (PAL)
Inner Barrel: 2.4/2.5mm
Outer Barrel: 5.5mm
Centre pin: Negative

Super Famicom (NTSC-J)
Inner Barrel: 2.1mm
Outer Barrel: 5.5mm
Centre pin: Negative

Come to think of it, I don’t think I’ve ever held a Super Famicom or Super Nintendo power supply. What strange times we live in! 🙂
